13、rds bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organ
14、izations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its f
15、urther maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/direc

31、d definitionsFor the purposes of this document, the terms and definitions given in ISO 11999-1 apply.4 General design requirementsFire hoods shall be classified as type FH1 and FH2, following the requirements specified in Clause 5 to Clause 7, with type FH2 providing higher protection. The fire hood
32、 shall be close fitting and able to be worn without discomfort or significant restriction to head movement. General requirements which are not specifically covered in this International Standard shall be in accordance with ISO 13688 and ISO 11999-1.Overstretching will reduce the heat protective perf
33、ormance of the hood and should be avoided by design.Where a helmet with shikoro provides coverage to the neck, ears, chin, and facial area not protected by a face shield, the use of a fire hood is not required.4.1 Facial openingThe fire hood shall have a facial opening creating an interface with the
34、 breathing apparatus facemask. The design requirements specified shall be verified by visual inspection during the procedure laid out in ISO/TS 11999-2.4.2 Yoke interface areaThe fire hood shall have a yoke creating an interface with the protective garment. The design requirements specified shall be
35、 verified by visual inspection during the procedure laid out in ISO/TS 11999-2.4.3 SizingThe firehood shall be manufactured in various sizes or be sufficiently elastic to be compatible with various head sizes and shapes. Assess by visual inspection.4.4 FlexibilityThe fire hood shall have flexibility
36、 to take up the shape of the wearers head without discomfort and shall not restrict head movement.4.5 Seam constructionSeams shall be constructed to give the minimum loss of strength and protection and to maintain the temperature resistance and integrity of the hood.5 Sampling and pre-treatment5.1 T
37、he number and size of specimens for the different tests shall be in accordance with the respective standard.2 ISO 2016 All rights reservedBS ISO 11999-9:2016ISO 11999-9:2016(E)5.2 Where specified, the test samples shall be pre-treated by cleaning. The cleaning shall be in line with the manufacturers
38、 instructions on the basis of standardized processes. If the number of cleaning cycles is not specified, the tests shall be carried out after five laundering cycles (one laundering cycle consisting of one washing and one drying) when laundering is specified, or after five cycles of dry cleaning when
39、 dry cleaning is specified. This shall be reflected in the information supplied by the manufacturer. If the manufacturers instructions indicate that both cleaning methods are allowed, the test specimen shall undergo the laundering procedure only.The test specimen shall undergo the laundering or dry
40、cleaning procedure, respectively depending on the extent and kind of dirt involved.Materials that are labelled as dry cleanable only shall be dry cleaned five times in accordance with ISO 3175-1.A laundry bag shall not be used.5.3 Unless otherwise specified in the specific test methods, all specimen
